editing: do we have 'column marking'? If not: enhancement proposal.

[newbie-02]

I frequently use a nifty feature in midnight commanders editor:

'column marking', invoked by shift-F3.

It toggles the normal marking 'all text between an anchoring point
and the actual cursor position' which we achieve by shift and cursoring,
or hold left button and mousing into marking a rectangular 'block'
between two points in a source, which then can be copied, deleted
or pasted to other positions.
Very very useful for editing in tables, e.g. moving columns from left to
right or vv., into another table, pull out, insert additional ...
I mean to remember that MS Word and LO Writer have similar features,
not actually checked, and assume similar in other old basic editors
like vim or emacs or ..., never used, not researched.
Enhancement proposal, AsciidocFX would be much better with this feature.

Pls. be tolerant if 'me bad', e.g. not found an existing feature, that's always
an option but not intentional.
